Anyone noticed that they're two completely different persons in the comic and in the TV series. The one from the comic series grieved with expressing honest emotions when Lori got killed unlike the TV series where Rick just tries to deny it or hallucinates shielding himself with various defense mechanisms. I do not think we will see him even weeping as much as one drop of tears for Lori. It shocked me how he changed on the road because you had to infer it. 

I would go to say that even right now in issue 107 Rick from the comic series is less detached emotionally than Rick from the TV series. It is mind blowing kinda for me. This totally different Rick in TV series bad as a badass is too Hollywood mainstream-ish for me. In the comic he keeps this unique personality that isn't exaggerated.
